Description
Technical field
This application involves automotive field more particularly to a kind of commercial vehicle protective devices.
Background technique
With continuous soaring, the highway communication increasingly congestion of China's car ownership, etesian vehicle collision accident
Also it remains high.Rear-end impact is crashed between vehicle and vehicle, such accident accounts for about the 33.4% of total accident, it
It can be subdivided into rear-end impact etc. of the passenger car to the rear-end impact of passenger car and passenger car to commercial vehicle again.Wherein, especially with
Passenger car knock into the back commercial vehicle collision accident it is the most serious.Large-scale cargo vehicle travel speed is relative to passenger car on highway
Travel speed it is slower, but its tail portion terrain clearance is larger, and rigidity and hardness are larger.The commercial vehicle if passenger car knocks into the back,
Collision is easily pierced, the collision of this form will cause greatly to threaten to the personal safety of driver and passenger in passenger car.
Commercial vehicle protecting device for rear lower part can play good buffering energy-absorbing function in rear-end impact, and can be effective
Blocking passenger car pierce the commercial vehicle tail portion back lower place, China emphasizes that commercial vehicle should install protecting device for rear lower part, and oneself pushes away
GB 11567.2-2017 standard is gone out.And there is also deficiencies for design on commercial vehicle Rear Underrun Protection Devices collision performance for the country, greatly
Most Rear Underrun Protection Devices are a simple rectangular tubes, and device rigidity is too small, not can effectively prevent after passenger car pierces commercial vehicle
Lower section cannot play the role of effective protection to riding passenger；Or device rigidity is excessive, touches although can play and prevent from piercing
The function of generation is hit, but the collision energy absorbed in collision is less, not can effectively reduce passenger car and its interior driver and passenger
Suffered injury in an impact.
